Planning Your Split Rail Fence Project

Planning a split rail fence project

The first step in any successful DIY home improvement project, including building a 3-rail wood fence, is thorough planning. Here are some of the steps you can follow before starting a rail fence installation project.

Identify Your Needs

Begin by clearly defining the purpose of your fence. Are you aiming to create a boundary for your property, or are you looking for a privacy fence to provide seclusion? Perhaps you’re interested in a horse fence for your equestrian needs. The type of fence you choose will largely depend on your specific requirements.

Choose Your Fence Materials

Once you’ve identified your needs, the next step is to decide on the fence materials. A wooden fence, for instance, offers a classic, rustic appeal that can enhance the aesthetic value of your property. On the other hand, a vinyl fence might be a more practical choice if you’re looking for durability with less maintenance. Remember, the choice of material can significantly influence the look and functionality of your fence.

Mark Your Property Lines

Accurate marking of your property lines is crucial to avoid disputes with neighbors and to ensure legal compliance. Use a tape measure to determine the exact boundaries of your property. This will help you plan the placement of your fence posts, including the corner posts and end posts.

Check with Utility Companies

Before you start digging holes for your fence posts with a post-hole digger, it’s important to check with your local utility companies. This is to ensure that you don’t accidentally hit any underground utility lines during the fence installation process.

Plan Your Post Locations

Planning post locations for split rail fence

Planning the locations of your line posts is a critical step in the fence installation process. You’ll need to consider the placement of the top rail, bottom rail, and any additional horizontal rails. This step requires careful measurement and marking to ensure that your fence is straight and secure.

Prepare Your Tools and Materials

Gather all the necessary tools and materials for your fence project. This includes a post level to ensure your posts are perfectly vertical, an auger for digging post holes, a concrete mix for setting your posts, and of course, your 3-rail wood fence materials.

Consider a Fence Gate

If you need access through your fence, don’t forget to plan for a fence gate. This will require additional planning and materials, but it’s an important feature for most fences.

Remember, a well-planned project is more likely to result in a successful outcome. So, take your time during this planning phase to ensure a smooth fence installation process. With hard work and careful planning, you’ll be well on your way to installing a 3-rail wood fence that you can be proud of.

Step-by-Step Fence Installation Process

As mentioned before, Installing a split rail wood fence can be a straightforward and rewarding DIY project. Here are 6 steps to help you install a 3-rail fence.

Step 1: Digging Post Holes

Digging post holes for fence installation

The first step in your fence project is to dig the post holes. Using a post hole digger or an auger, dig holes for your corner posts, end posts, and line posts. The depth of the holes will depend on the height of your fence and local building codes, but a general rule is to make them one-third the length of the post.

Step 2: Setting Corner and End Posts

Next, place the corner and end posts in the holes. Use a post level to ensure they are plumb. Then, fill the holes with concrete mix and tamp it down to remove any air pockets. Allow the concrete to set according to the manufacturer’s instructions. This usually takes about 24 to 48 hours.

Step 3: Installing Line Posts

Once the concrete has been set for the corner and end posts, you can start installing the line posts. Follow the same process as in Step 2. Make sure to use a string line to ensure the posts are aligned in a straight line. It’s also a good idea to periodically check the posts with a level as you work, to ensure they remain plumb.

Step 4: Attaching Rails

Attaching rails to a split rail fence

With the fence posts in place, you can start attaching the rails. Start from the rails that go at the bottom of the post followed by the middle and top rails. Make sure the rails are level and securely attached to the posts. You can use screws or nails to attach the rails to the posts. Please make sure that the rails are attached at the right height and evenly spaced, to give your fence a uniform appearance.

Step 5: Securing Bottom and Top Rails

After attaching the rails, check to ensure that the bottom and top rails are secure. They should be firmly attached to the posts and level. If necessary, make adjustments to ensure the stability of your fence.

Step 6: Adding Fence Gates for Access

What are some common mistakes to avoid when installing a 3-rail wood fence?

When starting a DIY fence project, many homeowners neglect a few things. These usually compromise the quality and durability of your fence. Here are some of the mistakes homeowners do that you need to avoid:

  1. Not Checking with Utility Companies: Before you start digging post holes, always check with your local utility companies to avoid hitting any underground lines. This is not only a safety issue but can also save you from costly repairs.
  2. Ignoring Property Lines: Use a tape measure to accurately mark your property lines before you start the fence installation. Installing a fence on your neighbor’s property can lead to legal issues.
  3. Improper Spacing of Fence Posts: The spacing between fence posts, including corner posts and end posts, is crucial for the stability of your fence. Posts that are too close together can make the fence weak, while posts that are too far apart can cause the fence to sag.
  4. Not Using a Level: Always use a post level when installing your fence posts to ensure they are plumb. An uneven fence is not only visually unappealing but can also be less stable.
  5. Failing to Secure Rails Properly: The top rail and bottom rail of your fence should be securely attached to the fence posts. Loose rails can lead to a wobbly fence.
  6. Not Planning for a Gate: If you need access through your fence, don’t forget to plan for a fence gate during the planning stage.


In conclusion, installing a 3-rail wood fence is a straightforward DIY project.
